Specification of Letters Patent.

Patented Apr. 3, 1917.

Original application filed February 16, 1911, Serial No. 608,869. Divided and this application filed April 2,

1912, Serial No. 688,063.

To all whom it may concern.

Be it known that I, CHARLES H. MUOKEN- HIRN', a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certaln new and useful Improvements in Water- Closet Bowls, of which the following is a specification, reference being had therein to the accompanying drawing.

This application is a division of my ap plica'tion Serial No. 608,869, filed February 16, 1911, and covering improvements in water closet bowls. v

The invention relates to water closets and has for its object the provision of an improved closet bowl of siphon character having a down leg for the discharge passage leading from the bowl, facilitating the formation of the water plug which is essential to the institution of a perfect and complete siphon discharge.

The preferred embodiment of the invention is illustrated in the accompanying drawings forming part hereof, and the characteristic features of the same will be apparent from an inspection of said drawings in connection with the detailed description hereinafter contained.

In the drawings,

Figure 1 is a vertical longitudinal section through the middle of the bowl,

Fig. 2 is a section along the line 4-4 of Fig. 1, and, I

Fig. 3 is a cross section on the line 5-5 of Fig. 1.

Referring more specifically to the drawings wherein like reference characters designate corresponding features in the several views, A represents the bowl, B the flushing rim, C the dam, D the uptake or leg and E the down leg leading to the ultimate discharge F. In keeping with the subject matter of my above referred to parent application I utilize the cycloidal surface of the bowl to effect the proper discharge by the passage of water up the leg D, but as this cycloidal formation constitutes no part of the present invention it need not be further considered herein.

The rear surface G of the discharge leg E is curved along its under run with a cycloid or a curve approaching a cycloid in character which causes the water that drops over Renewed February 6, 1917.

the dam to leap across the opening H of the final discharge outlet F from the point 12 to the surface above the point 13 (shown in the drawing as located slightly below the point 12, to allow for a slight drop of water by gravity at this point), but which lower location of the point 13 is not an essential feature to the action, as some part of the water leaping from the under run of the discharge conduit will strike above the point 13 and even above the level of the point 12 inasmuch as the water is in a mass and much of it is raised above the surface of the under run of the curve.

Some of the water leaps across the openmg 10, strikes the curved surface 15 and curves upward and backward, much of it adhering to the surface and following a curved path and some of it spattering or flylng, but nearly all of it remaining in the portion of the chamber which is above the direct outlet for an instant of time, and the water thus accumulates at this point before it changes its direction of movement downward through the ultimate outlet F. This change of movement and delay in time is sufficient to very promptly produce a Water plug at this point and as soon as the water plug is established the water tends to accumulate more and more and fill up the chamber E which now serves to store the excess of water passing over the dam exceeding for a short time the water escaping through the outlet F.

While I have herein illustrated a specific embodiment of the invention, it will be clear that the invention is capable of embodiment in other forms and devices.

I claim 1. In a water closet bowl, in combination with an up leg discharge outlet, a down leg discharge outlet having an under run curve approaching at the lower part of said curvature to the horizontal and approaching at the ultimate discharge outlet an extension of the chamber of the outlet leg lying opposite the terminal of the under run thereof and having its surface occupying an approximately vertical position but curved from a point approximately in the plane of said horizontal termination of the under run to substantially constitute a continuation of the curve of said under run to defiect water impinging thereon upward and backward to initially form a water plug in the ultimate outlet, substantially as described.

2. In a water closet bowl, in combination with an up leg discharge outlet, a down leg discharge outlet having an under run curve, substantially horizontal at its lower part, an ultimate outlet in the under run arranged at an angle thereto, the outlet leg being formed with an extension lying beyond the terminal of the under run thereof and having its surface curved in an approXimatelV Vertical direction from a point approXimately in the plane of said horizontal terminal of the under run to substantially constitute a continuation of the curve of said under run to deflect water impinging thereon upward and backward to initially form a' water plug in the ultimate outlet, the de- Gopies 0! this patent may be obtained for fleeting surface of the extension projecting downwardly slightly below the said terminal of the under run of the down leg.

3. In a water closet bowl, in combination with an up leg discharge outlet, a down leg discharge outlet, an ultimate outlet communicating with the lower end of the down leg discharge outlet, and an extension of the down leg discharge outlet having its inner wall curved and arranged beyond the ultimate outlet whereby water entering said extension will be directed upward and backward uponitself to initially form a water plug, substantially as described.

In testimony whereof I ailix my signature in presence of two witnesses.
